This study compared the impact of different treatments on health-related quality of life (HRQOL) among H1-antihistamine-refractory patients with chronic spontaneous urticaria. The results showed that hydroxychloroquine, ligelizumab, and omalizumab significantly improved HRQOL in these patients.
BACKGROUND: Recently, pharmacological treatment options for H1-antihistamine-refractory chronic spontaneous urticaria have increased dramatically; however, their effects on patient-reported outcomes, including health-related quality of life (HRQOL), remain unclear. OBJECTIVE: To compare the impact of these treatments on HRQOL among Hl-antihistamine-refractory patients with chronic spontaneous urticaria. METHODS: We completed a comprehensive search of the available literature in the electronic databases, gray literature, and preprint reports up to April 19, 2021, with no language restrictions. The primary outcome for evaluation was a change in HRQOL from the baseline, and secondary outcomes included patient unacceptability and other patient-reported outcomes. We used a random-effects network meta-analysis and estimated differences in standardized mean differences (SMDs) and odds ratios with 95% CIs. Evidence-based synthesis was based on magnitudes of effect size, evidence certainty, ranking of treatment effects, and clinically meaningful improvement. RESULTS: Twelve randomized controlled trials encompassing 1866 adolescent and adult patients were included. Our evidence synthesis analyses revealed that hydroxychloroquine (SMD, -1.00 [ -1.61 to - 0.39] ), 72 mg ligelizumab (SMD, -0.66 [ -0.96 to - 0.35] ), 240 mg ligelizumab (SMD, -0.67 [ -0.98 to - 0.37] ), and 300 mg omalizumab (SMD, -0.53 [-0.67 to -0.39]) significantly improved HRQOL with a moderate beneficial effect. However, the use of hydroxychloroquine seems to be limited by a higher risk of patient unacceptability of treatment. Other secondary outcomes remain inconclusive based on the available evidence. CONCLUSIONS: Both ligelizumab (72 or 240 mg) and 300 mg omalizumab appeared to be effective treatments for H1-antihistamine-refractory chronic spontaneous urticaria, because they were closely associated with improved HRQOL.
